Great tool before deep work sessions, instead of coffee and against parenting stress, especially lion’s breathing))) ### 5/5 — It’s really nice to see an honest app, not a scam *2026-01-30* It’s also much better than most other breathing apps. The breathing practices are designed in a very thoughtful and professional way. I’ve tried many other apps, and their exercises were often clunky or buggy. Here, everything works beautifully ### 5/5 — Thank you *2026-01-30* Nice app, helps me relax ## Frequently asked questions about Koru ### What is Koru?
